There is currently no ETA on adding red gear to the crafting bonus. It definitely will not be added in the event for awhile. However, they are working on compensation for everyone that crafted red gear during this event.

Compensation? Like what? The majority of people that would have brought up those heroes would have went ahead and farmed for the items regardless since they are failing on double crafting. Compensation like receiving these items in a mail is a bit useless for most if they've already brought them all up. Only logical compensation is stamina to the amount of farming all those items.
